Abstract

The invention discloses a preparation method of a maca extract. The method comprises the steps of: (1) maca extract liquid preparation; (2) maca extract liquid pretreatment; (3) ceramic membrane filtration; (4) vacuum concentration; and (5) spray drying. The content of an effective component glucosinolate in the extract provided by the invention can be improved by more than 3 times that of existing methods. Also, with the ceramic membrane filtration step, the physical and chemical characteristics of the maca effective component can be well preserved. With the method, product quality can be improved, production cost can be reduced, and environment can be protected. The method is beneficial for large-scale productions.

Description

technical field [0001] The invention relates to the extraction, separation and purification of plant effective components, in particular to a preparation method of maca extract. Background technique [0002] Maca, also known as Peruvian ginseng, maino, ayak chichira, ayakwillku, etc., is native to the South American Andes at an altitude of 3500-4500 meters, and its main production areas are Junin and Pasco in Peru. region, it is a plant of the genus Brassicaceae, often called Peruvian ginseng. Maca has been eaten in South America for more than 5,800 years. It is traditionally used as food and herbal medicine to improve sexual function, increase fertility, resist fatigue, fight tumors, and treat depression, asthma and women's menopausal syndrome. [0003] Maca is rich in protein, amino acids, sugars, minerals and multivitamins. In recent years, efficacy studies have shown that Maca has significant effects in improving fertility, anti-fatigue, and improving osteoporosis. As...
